10991131 divided by 23 
Our goal is to divide 10991131 by 23.

Moving on to step 1:
23 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 23

Moving on to step 2:
If we divide 10 by 23, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (9) from the dividend to 10 and continue with: 109 / 23

Step 3:
The number 23 fits into 109 4 times, leaving a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 17 after subtracting 92 from 109.
Append the next digit (9) from the dividend to 17 and continue with: 179 / 23

Going ahead to step 4:
23 goes into 179 7 times with a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 47.0
If we subtract 161 from 179, we get 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 23

Step 5:
23 can be fit into 181 7 times, resulting in a remainder of 20.
The number 7 becomes the next digit in our result. 
Result so far: 477.0
If we take 161 away from 181, we end up with 20.
Take the next digit (1) from the dividend and append it to 20, then repeat: 201 / 23

Going ahead to step 6:
201 divided by 23 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 4778.0
Deduct 184 from 201 and we're left with 17.
Fetch the next digit (3) from the dividend, attach it to 17 and continue: 173 / 23

Let's proceed to step 7:
23 can be fit into 173 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 47787.0
Deduct 161 from 173 and we're left with 12.
Fetch the next digit (1) from the dividend, attach it to 12 and continue: 121 / 23

Advancing to step 8:
When dividing 121 by 23, we get 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 477875.0
Deduct 115 from 121 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 23, we get 2 with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 477875.2
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 10:
If we divide 140 by 23, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 477875.26
Deduct 138 from 140 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 477875.26
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 477875.2608
The remainder is 16 after subtracting 184 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
23 goes into 160 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 477875.26086
Subtract 138 from 160 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 477875.260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 15:
23 goes into 130 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 477875.2608695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 16:
If we divide 150 by 23, we get 6 and a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 477875.26086956
Subtract 138 from 150 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 477875.26086956 with a remainder of 1.2e-08.
